TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. C; L`EwIs, of Auburn; in the State of New York, have invented certain new and usefullmprovenients in Wagon-Sent Clasps; and I do hereby declare that the\i`ollowingfis'a full and exact description of the same, reference being hed to the annexed drawings, and tothe letters of reference marke thereon, in which- Figure 1 is a perspective. Y N

AThe nature of my invention consists-in the employment and combination of the several devices hereinafter named for the lpurpose or" securing v\va.,vonsea.ts at any desired place on t'he sent-rail.

A represents a. plate of'inetal secured `tothe seat. B is a. lever pivoted to said plate, and is provided with 'a cam-shaped head, as shown in the drawings. On one side of this head is a. projection, for the purpose of preventing the lever Gfx-om slipping. i Said lever`s pivoted near its centre to plate A. The upper end of this laverie provided with a screw-thread cut through it. D represents the clasp, for holding the seat firmly in its place. This clasp is formed by having the lower end bent nt right angle withl the sbonk,A as partly seen in iig. I. The upper end of the shank is formed or cut into a. screw, so tha-t it will .ft the screw-thread in lever C. Thus it will be seen en et'eetve'nndsimple clasp is formed, which will hold the seat firmly in its place.

What I claim, and desire to secure by Letters Patent, isf-,-

The clasp D, levers B und C, constrxcted and arranged substnntially as and for the purpose set forth.

In testimony met I claim the above, I set my hand in presence of two. witnesses.
